It’s hard to see here but the too main walls containing the main living accomodation are actually curved. The main livingroom has a sunken area which will have wooden flooring i believe, while the hall area has stone slabs. The house is two storeys to the rear.
Perhaps an OD+T architect could post a plan.
Apologies for lack of interior shots but there were so many architects crawling over it, that all it would have resembled was an AAI yearbook 😉
